Through South Africa’s first collaborative project between a large scientific organisation, the Council for Scientific and Indust rial Research (CSIR), and the Traditional Healer’s Committee, Dicoma anomala was identified ...

As cyanobacteria (also known as blue green algae) produce a range of cyclic peptides which
are highly toxic, capillary electrophoresis and associated techniques have been investigated
to assess their applicability ...

This research effort investigated the activation of n-octane by oxidative dehydrogenation and
dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure
hydroxyapatite and iron substituted ...

The aims of this study were to characterise and quantify wood extractives in E. grandis and E.
nitens and determine the impact of wood extractives on pitch formation. Initially a comparison
was made with individual solvent ...

SAPPI SAJCCOR, whose factory is situated south of Durban, South Africa, is one of the
few paper and pulp mills that uses the acid sulphite process with calcium and magnesium
bases to produce a high-grade cellulose pulp. ...

Three species have been investigated in this project:
Iso-ocobullenone (p 23) and its probable precursor (p 27) have been isolated from the leaves and bark of Ocotea kenyensis. This is only the second time that these ...

Momordica foetida Schum. & Sond. (Cucurbitaceae), locally known as
iNtshungu, is widely used by the Zulu people of Natal-KwaZulu for the
treatment of a variety of ailments.
The dried leaves leaves and stems of this plant ...

Ledebouria ovatifolia (Bak.) lessop, Clivia caulescens R.A.Dyer and Haemanthus pauculifolius
Snijman & Van Wyk were the three species investigated in this work.
Ledebouria ovatifolia belongs to the family Hyacinthaceae ...

Ledebouria zebrina and Scilla natalensis Planch were the two species investigated in
this work. Ledebouria zebrina belongs to the Hyacinthaceae (Liliacea sensu lato) and to this
date, the chemical composition of this ...

Theoretical waste minimisation opportunities and options for electroplating were sought from the literature. Their suitability under the specific site conditions of a chromium electroplating plant were evaluated using the ...

The Fischer-Tropsch process in South Africa, used for producing chemicals from synthesis gas, which is mostly derived from the gasification of coal, gives a large amount of medium chain length alkanes (C4-C8), which have ...

A comparative study of the activation of n-hexane over the 12-molybdophopshoric acid (H3PMo12O40
or HPA), its Fe3+ doped salt (Fe0.69H0.93PMo12O40 or Fe doped HPA) and the iron phosphate catalyst
(P/Fe = 1.22) was carried ...

A comparative study of the activation of n-octane over nickel molybdate (α and β-phases), carbon nanotubes and carbon nanotube supported nickel molybdate was carried out in the gas phase in a plug flow fixed bed reactor ...

A comparative study was undertaken of different extraction methods for the isolation of
volatile organic compounds from Murraya koenigii (curry leaf plant). The techniques
studied included the traditional methods of ...

Co promoted and unpromoted vanadium-phosphorous-oxide (VPO) catalysts were synthesized via an organic route. The catalyst precursor was calcined and then conditioned in a reactor, forming the
active vanadyl pyrophosphate, ...
